See the Maintenance Section on page 12
of this manual for proper directions on
flushing the pump.
When the parts are reassembled, attach
the respirator and turn the pump on,
monitoring its performance for overheating.
5. The electrical circuit to which the pump is
connected is overloaded. Check the
amperage load of the circuit and discon-
nect other electrical equipment, if
necessary, from that circuit.
SYMPTOM: Outlet Air Temperature
Too Warm
1. Be sure that at least the first 50 feet (15 m)
of air supply hose closest to the pump is
laid out (not coiled) to permit excess heat
to dissipate from the hose.
2. Keep the air supply hose out of direct
sunlight and off warm or hot surfaces.
3. Put a coiled section of the air supply hose
in the bottom of a large container. Fill the
container with water and ice and cover with
a lid. For best results, locate the container
as close to the worker as possible.
SYMPTOM: Outlet Air Temperature
Too Cold
1. Let the pump warm up approximately 15
minutes before using.
2. Coil the first 25-50 feet (7.6-15 m) of air
supply hose closest to the pump.
3. Keep the air supply hose off cold surfaces.
SYMPTOM: Moisture In Air Supply
Hose Line
1.Locate the air inlet filter in a dry, clean air
location, where breathable air can be
assured at all times.
2. With the air supply hose connected to the
pump, but not the respirator, turn the pump
on and let it run for approximately 15
minutes to purge the hose of excessive
moisture.
